Edelweiss Oxygen 8.2mm 70m


The Edelweiss Oxygen 8.2mm is the highest performing half rope in the Edelweiss climbing rope range, and packs in all of the brands knowhow into one mega product.

Using the Perform3 and Unicore production methods Edelweiss have constructed a climbing rope which is both durable and light, whilst also maintaining excellent handling and safety stats.

Perform3 is a method of constructing the sheath and core using cutting edge, heat treated polymer technology. The linear molecular structure of these polymers means the handling and durability of Perform3 ropes is slick and ubiquitous. It also provides a gain in impact force performance - up to 12.5% on a similar diameter rope not using this technology.

Unicore technology is an impressive process, bonding rope sheath and core together without affecting the rope's handling. If the sheath is cut or torn, core and sheath will remain bonded and synchronised. With a non Unicore (or similar) rope, if the sheath is cut or badly abraded over an edge it will slip, exposing the core and the rope may even break if loaded.

The Edelweiss Super Everdry treatment provides a core deep barrier against water saturation. Each fibre is treated before the rope is woven, then the the rope is re-treated as a whole externally to make for a truly 'dry treated' product.

Finally, this rope also utilises 'HD Cover', a production process whereby the sheath yarns are braided individually (rather than in pairs or groups) making a tighter woven slicker sheath, which handles wonderfully and minimises 'grab' in belay devices. This reduced snagging on all surfaces also helps improve the ropes longevity and overall durability.
